28-10-2017 MONTE CORONA, VALENCIA - WALL BROWN BUTTERFLY (Lasiommata megera)

The species is common in continental Europe. It is also present in the Urals, south western Siberia, Asia Minor, Syria, Iran, Central Asia and the Himalayas. It is absent from the United Kingdom. Its preferred habitats are edges of the forest, unmanaged clearings on forested areas, rocky dry areas and stony slopes, at an elevation of 0–2,000 metres (0–6,562 ft) above sea level.

Lasiommata maera has a wingspan of 44–56 millimetres (1.7–2.2 in). These large butterflies are quite variable in color and pattern. Usually the upperside is orange in the forewings and mostly brown in the hindwings. The forewings always show a single ocellus, while the hindwings bear two or three ocelli. The underside of the forewings is orange and the underside of the hindwings is marbled with gray brown.[4] This species is quite similar to Lasiommata megera, that is smaller and has paler yellow-orange forewings. Seitz P. maera L. (= adrasta Dup.) (45 d). 

On an average larger than hiera, more evenly coloured, the black markings of the ground less prominent in the nymotypical form with a sooty brown disc; the forewing of the male more pointed, with longer costal margin and more oblique distal margin; on the underside of the forewing the distal band extends without interruption across the median veins to the hindmargin. The underside of the hindwing has a much purer ground-colour, i. e. there are less clouds and shadows between the various dentate lines which cross the disc. The apical ocellus has a stronger tendency towardsduplication being usually somewhat distorted obliquely and — at least beneath — bearing two pupils. Between this ocellus and the apex there is nearly always a minute eye-dot, there occurring also often specimens with other accessory ocelli . Moreover, the ocelli of the hindwing are as a rule somewhat larger than in the same sex of hiera — A very large material proves that it is hardly possible to find definite trenchant distinctions , especially if one takes into account the large number of local forms of maera, all the various kinds of pattern and coloration exhibiting a great variability.

28-10-2017 MONTE CORONA, VALENCIA - COAL TIT (Periparus ater)

The Coal tit (Periparus ater) is a small passerine bird widespread and common resident breeder throughout the temperate to subtropical Palearctic, including North Africa.

The Coal tit has a distinctive large white nape spot on its black head. The head, throat, and neck of the adult are glossy blue-black, setting off the off-white sides of the face (tinged grey to yellow depending on subspecies) and the brilliant white nape; the white tips of the wing coverts appear as two wingbars. The underparts are whitish shading through buff to rufous on the flanks. The bill is black, the legs lead-colored, and the irides dark brown. The young birds are duller than the adults, lacking gloss on the black head, and with the white of nape and cheeks tinged with yellow.

Coal tits are found throughout Europe, Asia, and North Africa. They are all-year residents throughout almost all range, making only local movements in response to particularly severe weather; only the Siberian birds have a more regular migration. Coal tits prefer humid conifer forests but also frequent shrubland, conifer plantations, gardens, and urban areas.

Coal tits are social birds and often form small flocks in winter with other tits. They resemble other tits in acrobatic skill and restless activity, though they more frequently pitch on a trunk, and in little hops resemble a treecreeper. Coal tits are active during the day spending most of their time searching for food trees. They also visit gardens to feed on a variety of foods put out, particularly sunflower seeds. While searching for food, Coal tit flocks keep contact with incessant short 'dee' or 'see-see' calls. Their song is a strident 'if-he, if-he, if-he', heard most frequently from January to June, but also in autumn. The song resembles that of the Great tit, but much faster and higher in pitch. North African birds also have a 'currr' call similar to that of the European crested tit which is not found in Africa.

Coal tits are herbivores (granivores) and carnivores (insectivores). They feed on various seeds, sap, insects, and spiders.

Coal tits breed once per year between March and late July. They prefer to nest in a hole in a rotting tree stump, often low down, and the nest is deep within the hole; holes in the ground, burrows of mice or rabbits, chinks between the stones in walls, old nests of Pica magpies or other large birds, and squirrel dreys are also occupied. The materials, moss, hair, and grass, are closely felted together, and rabbit fur or feathers are added for the lining. The female lays 7 to 11 red-spotted white eggs and incubates them for 14-16 days. The chicks hatch blind and helpless and remain in the nest for about 14 to 19 days.

27-10-2017 MONTE CORONA, VALENCIA - FIRECREST (Regulus ignicapilla)

The Common Firecrest, Regulus ignicapilla, is a diminutive passerine, a member of the kinglet family. It is characterized by its vibrant olive-green upperparts, with a distinctive bronze patch on each shoulder, and its underparts are a soft whitish hue, tinged with brownish-grey on the breast and flanks. The head is adorned with a striking pattern: a black eye stripe, a long white supercilium, and a crest that is a brilliant yellow in females and a vivid orange in males.

Adult firecrests are unmistakable with their bold head pattern and bronze shoulders. The male's orange crest and the female's yellow crest are particularly prominent during the breeding season. Juveniles can be identified by their grey-tinged upperparts and less vibrant head markings. The firecrest's flight is characterized as weak and whirring, with occasional quick, evasive turns.

The Common Firecrest favors broadleaved or coniferous woodland and gardens for breeding. It shows a preference for cork oak and alder in lowland broadleaf forests, but also inhabits mixed woodlands and various coniferous trees, often with undergrowth of juniper, ivy, and wild rose.

This species is found across most of temperate Europe and northwestern Africa. It is partially migratory, with central European birds wintering to the south and west of their breeding range. The Balearic Islands and north Africa host the subspecies R. i. balearicus, while the Madeira firecrest, previously considered a subspecies, is now recognized as a distinct species.

The Common Firecrest is a restless bird, constantly on the move as it forages. It often hovers while searching for insects and is known to join flocks of tits in winter. The species is monogamous, with males displaying their crests and engaging in a unique display during the breeding season.

The firecrest's call is a series of thin, high notes, slightly lower-pitched than those of its relative, the goldcrest. Its song consists of a repetition of these call notes in a longer and slightly more varied sequence, typically lasting 0.5–2.5 seconds.

The Common Firecrest breeds in a compact, three-layered nest on a tree branch. The female incubates a clutch of 7–12 eggs, and both parents feed the chicks. The young fledge 22–24 days after hatching.

The firecrest can be distinguished from similar species like Pallas's warbler by its brighter crest and face pattern. Juvenile firecrests might be confused with goldcrests but usually show enough facial pattern to be differentiated.

Firecrests feed on small arthropods such as springtails, aphids, and spiders. They exhibit a preference for larger prey compared to goldcrests and often forage while hovering. Parents feed young chicks with smaller prey initially, gradually introducing larger items as the chicks grow.

The Common Firecrest is classified as Least Concern by the IUCN. It has a large population, estimated at 10–15 million individuals, and its range has expanded over the last century. There are no significant conservation concerns for this species at present.

26-10-2017 MONTE CORONA, VALENCIA - LACEWING (Apertochrysa flavifrons)

A very common species, mostly flying between late June and August (strongly peaking in late July/early August) but I have recorded this species right up to the second half of October.

This is one of a group of relatively unmarked green lacewings that require examination of the hairs on the wing to identify. Firstly eliminate the Chrysoperla spp. (see Chrysoperla carnea for details - and remember, best to check both wings in case of abnormalities). Also check there is no black spot between the antennae and the second segment of the antennae is green. You are then left with the Nineta species, the commonest of which, vittata, is large and has a long swollen basal segment of the antennae. The other Nineta species are usually large (forewing >= 16mm) and if you happen across an unusually small example the species so far recorded in Norfolk has a concave costal edge to the forewing.

Unlike the similar Cunctochrysa species, flavifrons lacks a strong pale creamy stripe down the centre of the thorax and the hairs on the costa stick out more prominently. Compared to Chrysopidia ciliata these hairs are more angled, lying at around 45 degrees to the costa whereas they're closer to straight out on ciliata. The hairs on the costal cross-veins mostly point backwards but a few may point forwards too, however these hairs don't generally overlap like they do in ciliata as they are shorter. The palps are ringed with black whereas if they're dark at all on ciliata it should only be on the outer face.

26-10-2017 MONTE CORONA, VALENCIA - EURASIAN SISKIN (Spinus spinus)

The Eurasian siskin (Spinus spinus) is a small passerine bird in the finch family Fringillidae. It is also called the European siskin, common siskin or just siskin. Other (archaic) names include black-headed goldfinch, barley bird and aberdevine. It is very common throughout Europe and Eurosiberia. It is found in forested areas, both coniferous and mixed woodland where it feeds on seeds of all kinds, especially of alder and conifers.

It can be distinguished from other similar finches by the colour of the plumage. The upper parts are greyish green and the under parts grey-streaked white. Its wings are black with a conspicuous yellow wing bar, and the tail is black with yellow sides. The male has a mainly yellow face and breast, with a neat black cap. Female and young birds have a greyish green head and no cap. It is a trusting, sociable and active bird. The song of this bird is a pleasant mix of twitters and trills. For these reasons it is often raised in captivity.

These birds have an unusual migration pattern as every few years in winter they migrate southwards in large numbers. The reasons for this behaviour are not known but may be related to climatic factors and above all the availability of food. In this way overwintering populations can thrive where food is abundant. This small finch is an acrobatic feeder, often hanging upside-down like a tit. It will visit garden bird feeding stations.

The siskin was first described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae as Fringilla spinus, in the 10th edition of Systema Naturae. In 1760, Brisson described the genus Carduelis, where this species was then placed. Recent taxonomic studies suggest placing it in the genus Spinus.

The scientific name Spinus is from the Ancient Greek spinos, a name for a now-unidentifiable bird. The English name is from German dialect sisschen or zeischen,

Despite being found across a wide area it is a monotypic species, that is, there are no distinct subspecies. This could be explained by a number of factors, such as spatial variability of individuals in breeding areas between years, the large overwintering area which supports a constant genetic interchange, and females having a number of clutches of eggs in one breeding season, each in a different place.

This bird may have reached America either from Asia or from Europe (Greenland/Iceland). It is the extant parental species of one of the Spinus/Carduelis three evolutive North American radiations of atriceps, pinus and dominicensis finches. It has been recorded both in the Aleutian Islands and the east: the Labrador Peninsula and St. Lawrence River mouth (Canada). This raises the possibility that this bird entered (or may still try to enter) America through Greenland/Iceland from Western Europe.

The bird's appearance shows sexual dimorphism. The male has a greyish green back; yellow rump; the sides of the tail are yellow and the end is black; the wings are black with a distinctive yellow wing stripe; its breast is yellowish becoming whiter and striped towards the cloaca; it has a black bib (or chin patch) and on its head it has two yellow auriculas and a black cap. The amount of black on the bib is very variable between males and the size of the bib has been related to dominance within a flock. The plumage of the female is more olive-coloured than the male. The cap and the auriculas are greenish with a white bib and a rump that is a slightly striped whitish yellow. The young have a similar colouration to the females, with drab colours and a more subdued plumage.

The shape of the siskin's beak is determined by its feeding habits. It is strong although it is also slender in order to pick up the seeds on which they feed. The legs and feet are dark brown and the eyes are black.

It has a rapid and bounding flight pattern that is similar to other finches.

The siskin is easy to recognize, but in some instances it can be confused with other finches such as the citril finch, the European greenfinch or the European serin. The Eurasian siskin, in many plumages, is a bright bird. Adult male Eurasian siskins are bright green and yellow with a black cap, and an unstreaked throat and breast. Adult females also usually have green and yellow plumage tones: for example, yellow in the supercilium and on the sides of the breast, green tones in the mantle and yellow in the rump. The ground colour of the underparts of the Eurasian siskin is normally pure white. In females and juveniles, the centre of the belly and lower breast are often largely or entirely unstreaked. The wingbars of the Eurasian siskin are broad and yellow (with the tips white) and the bill is short with a decurved culmen.

The siskin is a small, short-tailed bird, 11–12.5 centimetres (4.3–4.9 in) in length with a wingspan that ranges from 20 to 23 centimetres (7.9 to 9.1 in). It weighs between 12 and 18 grams (0.42 and 0.63 oz).

This species can be found across the greater part of Eurosiberia and the north of Africa. Its breeding area is separated into two zones, both on each side of the Palearctic realm: the eastern coast of Asia and the central and northern part of Europe.

These birds can be found throughout the year in Central Europe and some mountain ranges in the south of the continent. They are present in the north of Scandinavia and in Russia and they over-winter in the Mediterranean basin and the area around the Black Sea. In China they breed in the Khingan Mountains of Inner Mongolia and in Jiangsu province; they spend winter in Tibet, Taiwan, the valleys of the lower Yangtse River and the south east coast.

The Eurasian siskin is occasionally seen in North America. There is also a similar and closely related North America counterpart, the pine siskin (Spinus pinus).

Their seasonal distribution is also marked by the fact that they follow an anomalous migration pattern. Every few years they migrate southwards in larger numbers and the overwintering populations in the Iberian Peninsula are greatly augmented. This event has been the object of diverse theories, one theory suggests that it occurs in the years when Norway spruce produces abundant seeds in the centre and north of Europe, causing populations to increase. An alternative theory is that greater migration occurs when the preferred food of alder or birch seed fails. This species will form large flocks outside the breeding season, often mixed with redpolls.

It is a bird that does not remain for long in one area but which varies the areas it uses for breeding and feeding, over-wintering from one year to the next.

Its habitat is forested areas at a particular altitude on a mountain side and they have a certain predilection for humid areas. Coniferous woodland, especially spruce, is favoured for breeding. It builds its nest in a tree, laying 2–6 eggs. The British range of this once local breeder has expanded greatly due to an increase in commercial conifer plantations. The siskin also breeds in mixed woodland; while in winter they prefer stubble and crops and areas containing trees with seeds.

They are very active and restless birds. They are also very social, forming small cohesive flocks especially in autumn and winter. They are fairly trusting of humans, it being possible to observe them from a short distance. During the breeding season, however, they are much more timid, solitary and difficult to observe. For this reason there is a German legend which says that siskins guard a magic stone in their nests that makes them invisible. It is one of the few species which has been described as exhibiting "allofeeding"' behavior, this is where subordinates (of the same sex) regurgitate food for the dominant members of the group, which creates a strong cohesion in the flocks and implies a hierarchical structure within the group.

25-10-2017 - RACO DE OLLA, VALENCIA - PIED AVOCET (Recurvirostra avosetta)

The pied avocet, Recurvirostra avosetta, presents a striking silhouette with its bold black and white plumage. This large wader, belonging to the avocet and stilt family, Recurvirostridae, is adorned with a distinctive black cap and black markings on its wings and back, contrasting sharply against its otherwise white body. The species is noted for its elegant, upturned bill and elongated, bluish legs, which add to its graceful demeanor.

Adult pied avocets measure approximately 16.5–17.75 inches in length, with a wingspan stretching around 30–31.5 inches. Their long legs and upturned bills, measuring about 2.95–3.35 inches and 3–4 inches respectively, are key features for identification. Both sexes appear similar, while juveniles can be distinguished by their more greyish and sepia tones.

These birds favor shallow lakes with brackish water and exposed mudflats, which provide ideal foraging and breeding grounds.

The pied avocet breeds across temperate Europe and extends across the Palearctic to Central Asia and the Russian Far East. It is a migratory species, with most individuals wintering in Africa or southern Asia. Some, however, remain in the milder parts of their range during winter, such as southern Spain and southern England.

Pied avocets forage in shallow waters or on mudflats, often employing a unique side-to-side scything motion with their bills to capture prey. They primarily consume crustaceans and insects. During the breeding season, they nest on open ground, often forming small groups and sometimes associating with other wader species. Their nests are typically lined scrapes or mounds of vegetation, where they lay three to five eggs.

The avocet's call is a distinctive, melodious "kluit kluit," which carries far across their watery habitats.

Pied avocets establish breeding territories in shallow brackish waters, where they lay their eggs in simple ground nests. These nests may be lined with materials or placed on mounds of vegetation to protect them from flooding.

While the pied avocet's unique plumage and bill shape make it quite distinctive, it could potentially be confused with other avocet species within the genus Recurvirostra. However, its black and white coloration and habitat preferences are usually sufficient for accurate identification.

The diet of the pied avocet consists mainly of crustaceans and insects, which they adeptly capture with their specialized bill.

The IUCN Red List classifies the pied avocet as Least Concern, indicating that, at present, the species does not face any imminent threats to its survival on a global scale.

23-10-2017 - MONTE CORONA, VALENCIA - LARGE PSAMMODROMUS LIZARD (Psammodromus algirus)

The Large Psammodromus lizard is a long, slender lizard which has incredible agility and speed. Their tails are very long and slim sometimes up to twice the length of the body, it’s limbs are also long and thin allowing short burst of high speed. It’s head is slightly pointed.

The lizard’s back is a soft milk-chocolate brown colour and there are two creamy -yellow stripes running down each flank. The back legs up to the base of the tail are a soft rust-orange colour. The body scales are somewhat ‘jagged’ keeled, pointed and almost upturned on each scale end.

Their subtle colouration camouflages them in the habitats they frequent, against the soil and dried vegetation under shrubs in forests, woodland or more open scrubland. They may be seen out in the open, but generally stick fairly close to shrubs that they can hunt through and use as cover and shelter.

Psammodromus lizards are very agile and climb nimbly through shrubs and hedges, sometimes giving away their position as they rustle through dry leaves.

This species  adapts readily to a variety of habitats from sea level up to around 2600m in altitude in the warmer southern areas of their distribution range.

Their diet consists mainly of arthropods – beetles, spiders, grasshoppers and ants, they will also eat other small lizards and fruit or seeds.

Breeding begins in the spring and there may be two or rarely three clutches consisting of between 2 to 11 eggs. The incubation time can vary from one to six weeks with the young appearing from August through to October. The young are 2.5 to 3cm in body length and have the same colouration and patterns as the adults. This species may live up to 7 years, reaching their sexual maturity when they are two years old.

25-10-2017 RACO DE OLLA, VALENCIA - PIED AVOCET (JUVENILE) (Recurvirostra avosetta)

Pied Avocet, scientifically known as Recurvirostra avosetta, is a unique bird species belonging to the Recurvirostridae family including avocets and stilts, some of the most fascinating waders for birding enthusiasts. These distinctive birds can be found across the Old World in a variety of climates and environments, including coastal areas, wetlands, and salt pans. An ideal spot to observe these birds would be in shallow water, where they often forage for food. The easiest way to identify Pied Avocets in the field is by their remarkable and unique upturned bills.

Pied Avocets are one of several species that appear on the emblem of the Royal Society for the Protection of Birds (RSPB) in the United Kingdom, where they symbolize nature conservation. Like all living things, they play a crucial role in the natural ecosystem. As wading birds, they help control insect populations and contribute to the overall health of wetland habitats. Like many other bird species, their presence can serve as an indicator of the quality of the environment.

Pied Avocets are medium-sized birds with an average length of 40-45 cm / 16-18 inches and a wingspan of 77-80 cm / 30-31 inches. They typically weigh around 240-315 g / 8.5-11 oz. These birds boast a distinct appearance that sets them apart from other waders.

As mentioned before, it is easiest to identify Pied Avocet by their long, thin, and upturned bills, which they use for sweeping through the water to catch small aquatic prey. Their black-and-white plumage provides a stark contrast, while the long, blue-grey legs further enhance their unique appearance. During the breeding season, these birds showcase an even more vibrant look making them particularly attractive to potential mates.

There are subtle differences between male and female Pied Avocets. Males tend to have slightly longer bills and legs, while females have more curved bills. However, these differences can be challenging to notice in the field, as both sexes share the same striking plumage.

Pied Avocets exhibit a preference for habitats such as coastal areas, wetlands, salt pans, and brackish lagoons. These environments provide an abundance of food resources and suitable nesting sites for the species. The choice of habitat is closely linked to the availability of shallow water, where Pied Avocets can efficiently forage using their specialized bills.

These birds are adapted to live in these environments, thanks to their long legs and unique bills, which enable them to wade and feed in shallow waters. Pied Avocets have a wide distribution, spanning parts of Europe, Asia, and Africa. They can be found in countries such as the United Kingdom, the Netherlands, France, Spain, Turkey, India, and South Africa, among others.

Pied Avocets exhibit both migratory and sedentary behaviors. Birds living in temperate regions usually migrate to warmer climates during the winter months, while those in milder or tropical regions tend to remain sedentary throughout the year.

Pied Avocets have a diverse diet primarily consisting of small aquatic invertebrates like insects, crustaceans, and mollusks. They may also consume small fish and plant material. Their unique upturned bills are perfectly adapted for their feeding techniques, which involve sweeping the bill side-to-side through shallow water to capture prey.

These birds display a fascinating feeding behavior known as “scything,” where they move their bills through the water in a scythe-like motion. As they do this, their sensitive bills detect the vibrations and movements of potential prey items, allowing them to efficiently locate and capture food.

Apart from scything, Pied Avocets also engage in other feeding techniques, such as probing the mud or sand for hidden invertebrates, and occasionally picking prey items from the water surface. This versatility in feeding strategies enables them to adapt to various habitats and food availability.

Pied Avocets have a fascinating breeding behavior. They form monogamous pairs that usually last for a single breeding season, although some may remain together for multiple seasons. Courtship displays between the male and female involve a series of ritualized postures, accompanied by high-pitched calls.

When it comes to nesting habits, Pied Avocets build their nests on the ground, typically in areas with sparse vegetation near shallow water. Nests are often simple scrapes in the ground, lined with pebbles, shells, or plant material. In some cases, they may build more elaborate nests on floating vegetation.

The female lays 3 to 4 eggs, which are incubated by both parents for approximately 23 to 25 days. Once the chicks hatch, they are precocial, meaning they are relatively mature and mobile. Both parents play an active role in protecting and caring for the chicks, which are able to feed themselves within hours of hatching. The young birds fledge after about 35 to 42 days, reaching sexual maturity at around one year of age.

25-10-2017 RACO DE OLLA, VALENCIA - LITTLE EGRET (Egretta garzetta)

The little egret (Egretta garzetta) is a species of small heron in the family Ardeidae. It is a white bird with a slender black beak, long black legs and, in the western race, yellow feet. As an aquatic bird, it feeds in shallow water and on land, consuming a variety of small creatures. It breeds colonially, often with other species of water birds, making a platform nest of sticks in a tree, bush or reed bed. A clutch of three to five bluish-green eggs is laid and incubated by both parents for about three weeks. The young fledge at about six weeks of age.

Its breeding distribution is in wetlands in warm temperate to tropical parts of Europe, Africa, Asia, and Australia. A successful colonist, its range has gradually expanded north, with stable and self-sustaining populations now present in the United Kingdom.

25-10-2017 RACO DE OLLA, VALENCIA - BLACK WINGED STILT (Himantopus himantopus)

Black-winged stilts (Himantopus himantopus) are very long-legged wading birds. They are found in both warm and hot climates, feed on small aquatic creatures, and nest on the ground surface in small colonies.Adult Black-winged stilts have long, pink legs, and a long, rather thin black bill. They are generally black above and white below, with a white head and neck. Males have a black back, often with a greenish gloss or sheen. Females' backs have a brownish hue, contrasting with the black remiges. In populations where the top of the head is normally white (at least in winter), females tend to have less black on the head and neck the entire year round, while males often have much more black, particularly in summer. This difference is not clear-cut, however, and males usually grow all-white head feathers in winter. Immature birds are grey, instead of black, and have a markedly sandy hue on their wings, with light feather fringes appearing as a whitish line in flight.

25-10-2017 RACO DE OLLA, VALENCIA - RUFF (Calidris pugnax)

The Ruff, Calidris pugnax, is a medium-sized wading bird known for its remarkable breeding plumage and sexual dimorphism. Males, significantly larger than females, boast ornate ruffs and head tufts in a variety of colors during the breeding season. Females, referred to as "reeves," are more subdued in coloration. The species exhibits a pot-bellied profile, with a small head and long neck, and displays a distinctive flight pattern with a slow wingbeat.

In breeding plumage, males are unmistakable with their bright ruffs and head tufts, which can be black, chestnut, or white. Females and non-breeding males are more cryptic, with grey-brown upperparts and mainly white underparts. Juveniles resemble non-breeding adults but have a buff tinge to their plumage. The ruff's long legs vary in color from greenish in juveniles to pink or orange in adults.

Ruffs breed in marshes and wet meadows across northern Eurasia. They prefer hummocky marshes and deltas with shallow water for feeding and dry areas with sedge or low scrub for nesting.

This migratory species breeds from Scandinavia and Great Britain to the Pacific, with the largest numbers in Russia and Scandinavia. In winter, they are found in southern and western Europe, Africa, southern Asia, and parts of Australia.

Ruffs are highly gregarious, especially during migration when they form large flocks. Males display at leks, with territorial males occupying small areas and satellite males attempting to mate within these territories. A third, rare male type mimics females to gain mating opportunities.

The ruff is generally silent, but during display, a soft "gue-gue-gue" may be heard.

Females lay four eggs in a well-hidden ground nest and incubate them alone. Chicks are mobile soon after hatching and are reared solely by the female. Males leave the breeding grounds early in the season.

Juvenile sharp-tailed sandpipers and buff-breasted sandpipers can be confused with juvenile ruffs but differ in size, shape, and plumage details.

Ruffs feed on insects, especially during the breeding season, and consume plant material, including rice and maize, during migration and winter. They forage in wet grassland and soft mud, probing or searching by sight for edible items.

25-10-2017 RACO DE OLLA, VALENCIA - BLACK WINGED STILT (JUVENILE) (Himantopus himantopus)

Black-winged stilts (Himantopus himantopus) are very long-legged wading birds. They are found in both warm and hot climates, feed on small aquatic creatures, and nest on the ground surface in small colonies.

Adult Black-winged stilts have long, pink legs, and a long, rather thin black bill. They are generally black above and white below, with a white head and neck. Males have a black back, often with a greenish gloss or sheen. Females' backs have a brownish hue, contrasting with the black remiges. In populations where the top of the head is normally white (at least in winter), females tend to have less black on the head and neck the entire year round, while males often have much more black, particularly in summer. This difference is not clear-cut, however, and males usually grow all-white head feathers in winter. Immature birds are grey, instead of black, and have a markedly sandy hue on their wings, with light feather fringes appearing as a whitish line in flight.

25-10-2017 RACO DE OLLA, VALENCIA - BLACK TAILED GODWIT (Limosa limosa)

The black-tailed godwit (Limosa limosa ) is a large, long-legged, long-billed shorebird first described by Carl Linnaeus in 1758. It is a member of the godwit genus, Limosa. There are four subspecies, all with orange head, neck and chest in breeding plumage and dull grey-brown winter coloration, and distinctive black and white wingbar at all times.

Its breeding range stretches from Iceland through Europe and areas of central Asia. Black-tailed godwits spend (the northern hemisphere) winter in areas as diverse as the Indian subcontinent, Australia, New Zealand, western Europe and west Africa. The species breeds in fens, lake edges, damp meadows, moorlands and bogs and uses estuaries, swamps and floods in (the northern hemisphere) winter; it is more likely to be found inland and on freshwater than the similar bar-tailed godwit. The world population is estimated to be 634,000 to 805,000 birds and is classified as Near Threatened. The black-tailed godwit is the national bird of the Netherlands.

The black-tailed godwit is a large wader with long bill (7.5 to 12 cm (3.0 to 4.7 in) long), neck and legs. During the breeding season, the bill has a yellowish or orange-pink base and dark tip; the base is pink in winter. The legs are dark grey, brown or black. The sexes are similar, but in breeding plumage, they can be separated by the male's brighter, more extensive orange breast, neck and head. In winter, adult black-tailed godwits have a uniform brown-grey breast and upperparts (in contrast to the bar-tailed godwit's streaked back). Juveniles have a pale orange wash to the neck and breast.

In flight, its bold black and white wings and white rump can be seen readily. When on the ground it can be difficult to separate from the similar bar-tailed Godwit, but the black-tailed godwit's longer, straighter bill and longer legs are diagnostic. Black-tailed godwits are similar in body size and shape to bar-taileds, but stand taller.

It measures 42 cm (17 in) from bill to tail with a wingspan of 70–82 cm (28–32 in). Males weight around 280 g (9.9 oz) and females 340 g (12 oz). The female is around 5% larger than the male, with a bill 12–15% longer.

The most common call is a strident weeka weeka weeka.

A study of black-tailed godwits in the Netherlands found a mortality rate of 37.6% in the first year of life, 32% in the second year, and 36.9% thereafter.

Black-tailed godwits have a discontinuous breeding range stretching from Iceland to the far east of Russia. Their breeding habitat is river valley fens, floods at the edges of large lakes, damp steppes, raised bogs and moorlands. An important proportion of the European population now uses secondary habitats: lowland wet grasslands, coastal grazing marshes, pastures, wet areas near fishponds or sewage works, and saline lagoons. Breeding can also take place in sugar beet, potato and rye fields in the Netherlands and Germany.

In spring, black-tailed godwits feed largely in grasslands, moving to muddy estuaries after breeding and for winter. On African wintering grounds, swamps, floods and irrigated paddy fields can attract flocks of birds. In India, inland pools, lakes and marshes are used, and occasionally brackish lakes, tidal creeks and estuaries.

Godwits from the Icelandic population winter mainly in the United Kingdom, Ireland, France and the Netherlands, though some fly on to Spain, Portugal and perhaps Morocco. Birds of the limosa subspecies from western Europe fly south to Morocco and then on to Senegal and Guinea-Bissau. Birds from the eastern European populations migrate to Tunisia and Algeria, then on to Mali or Chad. Young birds from the European populations stay on in Africa after their first winter and return to Europe at the age of two years. Asian black-tailed godwits winter in Australia, Taiwan, the Philippines, Indonesia, and Papua New Guinea.

Black-tailed godwits are much more likely to be found on inland wetlands than the more coastal bar-tailed godwit. They migrate in flocks to western Europe, Africa, south Asia and Australia. Although this species occurs in Ireland and Great Britain all year-round, they are not the same birds. The breeding birds depart in autumn, but are replaced in winter by the larger Icelandic race. These birds occasionally appear in the Aleutian Islands and, rarely, on the Atlantic coast of North America.

25-10-2017 DEVESA, VALENCIA - GREY HERON (Ardea cinerea)

The grey heron (Ardea cinerea) is a long-legged wading bird of the heron family, Ardeidae, native throughout temperate Europe and Asia, and also parts of Africa. It is resident in much of its range, but some populations from the more northern parts migrate southwards in autumn. A bird of wetland areas, it can be seen around lakes, rivers, ponds, marshes and on the sea coast. It feeds mostly on aquatic creatures which it catches after standing stationary beside or in the water, or stalking its prey through the shallows.

Standing up to 1 metre (3 ft 3 in) tall, adults weigh from 1 to 2 kg (2 to 4 lb). They have a white head and neck with a broad black stripe that extends from the eye to the black crest. The body and wings are grey above and the underparts are greyish-white, with some black on the flanks. The long, sharply pointed beak is pinkish-yellow and the legs are brown.

The birds breed colonially in spring in heronries, usually building their nests high in trees. A clutch of usually three to five bluish-green eggs is laid. Both birds incubate the eggs for around 25 days, and then both feed the chicks, which fledge when 7-8 weeks old. Many juveniles do not survive their first winter, but if they do, they can expect to live for about 5 years.

In Ancient Egypt, the deity Bennu was depicted as a heron in New Kingdom artwork. In Ancient Rome, the heron was a bird of divination. Roast heron was once a specially prized dish; when George Neville became Archbishop of York in 1465, 400 herons were served to the guests.

25-10-2017 DEVESA, VALENCIA - GREATER FLAMINGO (JUVENILE) (Phoenicopterus roseus)

The Greater flamingo (Phoenicopterus roseus) is the most widespread and largest species of the flamingo family. It was described by Peter Simon Pallas in 1811. The Greater flamingo was previously thought to be the same species as the American flamingo, but because of coloring differences of its head, neck, body, and bill, the two flamingos are now most commonly considered separate species.

Greater flamingos have an attractive coloration and appearance. Their feathers are pinkish/white, the wing coverts are red and the primary and secondary flight feathers are black. They have long pink bills with a black tip, yellow eyes and long pink legs. The male is bigger than the female, and juveniles have a gray-brown coloration, with some pink on their underparts, tail and wings, with the legs and beak being mainly brown.

25-10-2017 DEVESA, VALENCIA - BLACK NECKED GREBE (Podiceps nigricollis ssp. nigricollis)

The black-necked grebe or eared grebe (Podiceps nigricollis ) is a member of the grebe family of water birds. It was described in 1831 by Christian Ludwig Brehm. There are currently three accepted subspecies, including the nominate subspecies. Its breeding plumage features a distinctive ochre-coloured plumage which extends behind its eye and over its ear coverts. The rest of the upper parts, including the head, neck, and breast, are coloured black to blackish brown. The flanks are tawny rufous to maroon-chestnut, and the abdomen is white. When in its non-breeding plumage, this bird has greyish-black upper parts, including the top of the head and a vertical stripe on the back of the neck. The flanks are also greyish-black. The rest of the body is a white or whitish colour. The juvenile has more brown in its darker areas. The subspecies californicus can be distinguished from the nominate by the former's usually longer bill. The other subspecies, P. n. gurneyi, can be differentiated by its greyer head and upper parts and by its smaller size. P. n. gurneyi can also be told apart by its lack of a non-breeding plumage. This species is present in parts of Africa, Eurasia, and the Americas.

The black-necked grebe uses multiple foraging techniques. Insects, which make up the majority of this bird's diet, are caught either on the surface of the water or when they are in flight. It occasionally practices foliage gleaning. This grebe dives to catch crustaceans, molluscs, tadpoles, and small frogs and fish. When moulting at saline lakes, this bird feeds mostly on brine shrimp. The black-necked grebe makes a floating cup nest on an open lake. The nest cup is covered with a disc. This nest is located both in colonies and by itself. During the breeding season, which varies depending on location, this species will lay one (sometimes two) clutch of three to four eggs. The number of eggs is sometimes larger due to conspecific brood parasitism. After a 21-day incubation period, the eggs hatch, and then the nest is deserted. After about 10 days, the parents split up the chicks between themselves. After this, the chicks become independent in about 10 days, and fledge in about three weeks.

Although it generally avoids flight, the black-necked grebe travels as far as 6,000 kilometres (3,700 mi) during migration. In addition, it becomes flightless for two months after completing a migration to reach an area where it can safely moult. During this moult, the grebe can double in weight. The migrations to reach these areas are dangerous, sometimes with thousands of grebe deaths. In spite of this, it is classified as a least concern species by the International Union for Conservation of Nature (IUCN). It is likely that this is the most numerous grebe in the world. There are potential threats to it, such as oil spills, but these are not likely to present a major risk to the overall population.

The black-necked grebe usually measures between 28 and 34 centimetres (11 and 13 in) in length and weighs 265 to 450 grams (9.3 to 15.9 oz). The bird has a wingspan range of 20.5-21.6 in (52-55 cm). The nominate subspecies in breeding plumage has the head, neck, breast, and upper parts coloured black to blackish brown, with the exception of the ochre-coloured fan of feathers extending behind the eye over the eye-coverts and sides of the nape. This eye is mostly red, with a narrow and paler yellow ring on the inner parts of the eye and an orange-yellow to pinkish-red orbital ring. The thin, upturned bill, on the other hand, is black, and is connected to the eye by a blackish line starting at the gape. Sometimes, the foreneck can be found to be mostly tinged brown. The upperwing is blackish to drab brown in colour and has a white patch formed by the secondaries and part of the inner primaries. The flanks are coloured tawny rufous to maroon-chestnut and have the occasional blackish fleck. The underwing and abdomen is white, with an exception to the former being the dark tertials and the mostly pale grey-brown outer primaries. The legs are a dark greenish grey. The sexes are similar.

In non-breeding plumage, the nominate has greyish-black upper parts, cap, nape, and hindneck, with the colour on the upper portion of the latter being contained in a vertical stripe. The dark colour of the cap reaches below the eye and can be seen, diffused, to the ear-coverts. Behind the ear-coverts on the sides of the neck, there are white ovals. The rest of the neck is grey to brownish-grey in colour and has white that varies in amount. The breast is white, and the abdomen is whitish. The flanks are coloured in a mix of blackish-grey with white flecks. The colour of the bill when not breeding differs from that of the breeding plumage, with the former being significantly more grey.

The juvenile black-necked grebe is similar to the non-breeding adult. There are differences, however, including the fact that the dark areas are usually more brownish in the juvenile, with less black. The lores are often tinged pale grey, with whitish marks behind the eye. On the sides of the head and upper neck, there is a buffy or tawny tinge. The chick is downy and has a blackish-grey head with stripes and spots that are white or pale buff-grey. The throat and foreneck are largely pale. The upper parts are mostly dark grey in colour, and the abdomen is white.

24-11-2017 MONTE CORONA, VALENCIA - SESAME LEAFROLLER (Antigastra catalaunalis)

Antigastra catalaunalis is a species of moth of the family Crambidae. The species was first described by Philogène Auguste Joseph Duponchel in 1833. It is endemic to tropical and subtropical areas (South Asia, Malay Archipelago, Africa), but is also found in other areas due to its migratory nature.

The wingspan is 19–22 mm. The forewings are pale yellow, veins and margins suffused with ferruginous, sometimes almost obscuring ground-colour; lines ferruginous, second strongly curved outwards on upper 2/3 ; small orbicular and discal spot fuscous ; cilia whitish, base dark fuscous. Hindwings are yellow whitish, ferruginous-tinged, termen more ferruginous ; a cloudy grey postmedian costal spot.

The larvae feed on snapdragons (Antirrhinum species), common toadflax (Linaria vulgaris), trumpetbush (Tecoma species), Scrophulariaceae and Pedaliaceae species.
